Copilot Studio: 4 Ways to Tune Dataverse

Key insights

• Copilot Studio connects to Dataverse and uses Retrieval Augmented Generation (RAG) so agents ground answers in real enterprise data.
  
• Multiline Text and File Columns support lets agents surface information from long notes and attached documents without manual extraction, improving relevance.
  
• Column Management and refined synonym lists reduce noise by focusing retrieval on the most relevant fields, which raises answer accuracy.
  
• Natural Language Understanding (NLU) customization allows makers to define topics and entities, so agents resolve queries faster and make fewer mistakes.
  
• Model Context Protocol (MCP) and integrations (including Azure AI Foundry) let you extend agents with custom tools or fine-tuned models while preserving schema and data flow.
  
• Microsoft Information Protection and built-in governance keep data secure, and ROI analytics help measure time and cost savings from agent use.
  

Introduction

The YouTube video by Sean Astrakhan (Untethered 365) examines how to get super accurate results from Copilot Studio when it queries enterprise data in Dataverse. The presenter frames this as a set of four practical techniques—glossaries, settings, Azure AI Search, and Azure Functions—rather than a single toggle or feature. Consequently, the video emphasizes that makers must combine configuration, indexing, and light custom code to reliably improve agent responses. Overall, the piece targets architects and makers who need grounded, business-accurate conversational AI.

How Copilot Studio Interacts with Dataverse

Sean explains that Copilot Studio uses a Retrieval Augmented Generation approach, commonly called RAG, to pull relevant data from Dataverse and then generate answers. Thus, the quality of responses depends heavily on which fields are indexed and how those fields are interpreted by the system. Moreover, the platform now supports multiline text and file column searches, allowing agents to surface insights buried in notes and documents. As a result, organizations can expect more context-aware replies when they properly prepare their data sources.

The video also highlights extensibility through protocols and connectors, including the Model Context Protocol and external compute hooks. This lets teams call custom AI models or run logic before and after retrieval, which can be useful for validation or enrichment. However, integrating those pathways increases system complexity and requires careful schema validation and governance. Therefore, teams must balance the benefits of richer context with the need for secure, maintainable design.

The Four Techniques That Improve Accuracy

First, Sean covers glossaries and synonym lists, which standardize domain terms so the agent recognizes local jargon and acronyms. He advises curating these lists to reduce ambiguous matches and to help the model map user language to stored facts. Secondly, the right settings—including which columns to index and how to weight them—can dramatically reduce noise and steer retrieval to the most relevant records. Consequently, precision improves when makers deliberately limit retrieval to meaningful fields.

Third, leveraging Azure AI Search provides semantic indexing and relevance tuning for long-form text and files, which helps surface passages rather than entire documents. Finally, lightweight serverless hooks such as Azure Functions can transform queries or post-process results to enforce business rules or to merge facts from multiple sources. Taken together, these techniques form a layered architecture that increases containment and reduces incorrect or vague answers.

Tradeoffs When Balancing Accuracy, Cost, and Complexity

Achieving higher accuracy usually comes with tradeoffs in cost, latency, and operational overhead, as Sean points out. For example, deeper indexing and frequent re-indexing of large file columns can raise storage and compute bills while also increasing refresh time. Similarly, adding Azure Functions or external models improves logic and validation but introduces potential points of failure and extra maintenance.

Conversely, a minimal setup reduces cost and complexity but risks lower containment and more follow-up queries from users. Therefore, teams should weigh immediate business value against long-term support costs and choose a phased approach. In other words, start with targeted scenarios that show clear ROI and then expand indexing and automation as confidence grows.

Challenges and Practical Recommendations

Sean emphasizes several challenges, such as handling noisy multiline notes, protecting sensitive information, and keeping synonyms up to date as business terms evolve. He also warns that overly broad column selection leads to irrelevant matches and that poor NLU customization makes the agent brittle in real conversations. Thus, ongoing monitoring and tuning are essential to maintain performance over time.

As practical advice, the video recommends beginning with a pilot that focuses on a single business process, curating the indexed columns closely, and validating results with real users. Moreover, use Azure AI Search for semantic retrieval on text-heavy fields and reserve Azure Functions for tasks that need deterministic post-processing. Finally, instrument runs for ROI metrics and for security labels so teams can measure benefit while staying compliant.

Conclusion

In summary, the YouTube video by Sean Astrakhan (Untethered 365) outlines a pragmatic, layered approach to improving Copilot Studio’s accuracy with Dataverse data. It shows that combining curated glossaries, precise settings, semantic search, and selective serverless logic yields the best results in many enterprise scenarios. However, these gains require deliberate tradeoffs around cost, latency, and operational complexity that teams must manage actively.

Therefore, organizations should pilot focused use cases, monitor outcomes, and iterate on glossaries and column choices. Ultimately, the video presents an actionable roadmap for makers who want to move from experimental agents to reliable, business-ready Copilots.
